NOTE: Depending on size of onedrive storage used, it can take several minutes for all the files to be processed, they are not being downloaded at this time but stubs file are created rather that the full file.

Accessing Files on Demand

  • Accessing OneDrive is accessed as normal from the File Explorer

Observations/Comments :

  • During the setup of OneDrive account, there is no option to select File on-demand during that process so essentially it would automatically go into a state of downloading all files to cache
    • I choose not to sync files/folders, Selected file on-demand option and then added the folder’s to sync to ensure it did not start caching
  • Location of data is unchanged %USERPROFILE%\OneDrive -[tenantname] , both stubs/cached files are stored there from what i have seen
  • Blank folders will appear locally available
  • Thumbnails are generated for file formats which allow this without downloading the file
  • Searching of files is possible by name , but contents are not searchable
